BACKGROUND

Allergy is a disorder of the immune system and is characterized by theoccurrence of allergic reactions to normally harmless environmentalsubstances. Allergies are caused by allergens, which may be present in awide variety of sources, including but not limited to pollens or otherplant components, dust, molds or fungi, foods, additives, latex,transfusion reactions, animal or bird danders, insect venoms,radiocontrast medium, medications or chemicals. Common allergicreactions include eczema, hives, hay fever, asthma, and reactions tovenoms. Mild allergies like hay fever are highly prevalent in the humanpopulation and cause symptoms such as allergic conjunctivitis,itchiness, and runny nose. In some people, severe allergies toenvironmental or dietary allergens or to medication may result inlife-threatening anaphylactic reactions and potentially death, if leftuntreated. Allergic reactions can occur in three distinct patterns: a)an early phase reaction or acute response, b) late phase reactions andc) potentially chronic allergic inflammation. The early phase of theallergic reaction typically occurs within minutes, or even seconds,following a first allergen exposure, where this early phase is alsocommonly referred to as the immediate allergic reaction. In the earlystages of allergy, a hypersensitivity reaction against an allergen,encountered for the first time, causes a response in Th2 cells, whichare a subset of T cells that produce the cytokine interleukin-4 (IL-4).The Th2 cells interact with B cells (lymphocytes that produce antibodiesagainst antigens) and, coupled with the effects of IL-4, stimulate the Bcells to begin production and secretion of Immunoglobulin E (IgE).

IgE plays an important role in allergies and allergic reactions. Uponintroduction of an allergen, B cells of the respective subject producelarge amounts of IgE. The IgE elicits an immune response by binding ontoreceptors found on basophils and mast cells. When activated, these cellsrelease chemical mediators such as histamine and cytokines that causethe characteristic symptoms of allergy.

A food allergy is an adverse immune response to a food allergen, e.g., afood protein. Common food allergens are found in shellfish, peanuts,tree nuts, fish, milk, eggs, soy and fresh fruits such as strawberries,mango, banana, and apple. Immunoglobulin E (IgE)-mediated food allergiesare classified as type-I immediate hypersensitivity reactions. Theseallergic reactions have an acute onset (from seconds to one hour) andthe accompanying symptoms may include angioedema (soft tissue swellingof the eyelids, face, lips, tongue, larynx and trachea); hives; itchingof the mouth, throat, eyes, or skin; gastrointestinal symptoms such asnausea, vomiting, diarrhea, stomach cramps, or abdominal pain;rhinorrhea or nasal congestion; wheezing, shortness of breath, ordifficulty swallowing; and even anaphylaxis, a severe, whole-bodyallergic reaction that can result in death. Gupta, et al. (PEDIATRICSVol. 128 No. 1 Jul. 1, 2011 pp. e9 -e17) demonstrated that 1 out of 12children under the age of 21 years of age have a doctor's diagnosis offood allergies. This epidemic has been reported to be doubling every 10years for certain nuts (CDC 2009). Moreover, there are still deaths thatoccur every year due fatal food allergies. Importantly, over $24 billionis spent per year on health care/care costs for food allergic reactions(Gupta, et al. JAMA PEDIATRICS November 2013, Vol. 167, No. 11). Thiscost is largely due to about 90,000 visits to the ER per year in theU.S. due to food induced anaphylactic symptoms.

Mixed Allergen Compositions

As summarized above, aspects of the invention include mixed allergencompositions. By mixed allergen composition is meant a composition thatincludes two or more different allergens, where any two given allergensare different if they are distinct from each other, e.g., they arecompounds described by different chemical formula or compositionsdescribed by different components (e.g., constituent compounds) and/oramounts thereof. The number of different allergens in a composition mayvary, as desired. In certain embodiments, the mixed allergencompositions include 2 more different allergens, such as 3 or moredifferent allergens, 4 or more different allergens, 5 or more differentallergens, 6 or more different allergens, 7 or more different allergens,8 or more different allergens, 9 or more different allergens, 10 or moredifferent allergens, 15 or more different allergens, 20 or moredifferent allergens, 25 or more different allergens, 30 or moredifferent allergens, 40 or more different allergens, 50 or moredifferent allergens, 75 or more different allergens, 100 or moredifferent allergens, where in some instances the number of differentallergens in a given composition is 100 or less, such as 75 or less,including 50 or less, e.g., 25 or less, 15 or less, including 10 orless. In certain embodiments, a composition may comprise 2 to 20different protein allergens, or e.g., 2 to 100 different allergens, ore.g., 2 to 1000 different allergens. In further embodiments, acomposition may comprise 6 to 20 different protein allergens/proteinallergen compositions. In certain embodiments, a composition may consistessentially of 2 to 20 different protein allergens, or e.g., 2 to 100different allergens, or e.g., 2 to 1000 different allergens.

Allergens present in the composition may vary, where in some instancesthe allergen present in the composition is one that induces an allergyin a susceptible subject. Allergens include any antigen, or activederivative thereof, that elicits a specific IgE response. Antigensinclude any substance that can stimulate the production of antibodiesand can combine specifically with them. Antigenic determinants orepitopes are antigenic sites on a molecule. Allergens may have little orno intrinsic toxicity by themselves, but cause a pathological conditiondue to their ability to elicit an IgE-associated immune response, and,upon subsequent exposure, due to their ability to elicit IgE- and/or Tcell-dependent hypersensitivity reactions. As such, an “allergen”includes any substance which is capable of stimulating a typicalhypersensitivity reaction in atopic subjects. Allergens that may bepresent in a given mixed allergen composition include any substancefound in a variety of different sources, such as but not limited to:foods, drugs, perfume, plants, the environment or biological systems(e.g., prokaryotic or eukaryotic cells or viruses), as well as chemicalallergens.

The amount of a given allergen in a mixed allergen composition may vary,as desired. In some instances, the amount of a given allergen rangesfrom about 1 to about 15,000 mg, about 5 to about 15,000 mg, about 10 toabout 10,000 mg, about 15 to about 5,000 mg, about 10 to about 100 mg,or about 15 to about 100 mg. The weight percentage of a given allergenin a mixed allergen composition may vary, ranging in some instances fromabout 0.1 to about 99.9 wt. %, about 0.1 to about 15 wt. %, about 0.1 toabout 99.9 wt. %, about 15 to about 99.9 wt. %, or about 25 to about 65wt. %. The amount of a given allergen in a mixed allergen compositionmay be recited by total mass, or by protein mass, which may vary for agiven allergen depending upon the weight percentage of protein in thatallergen.

A mixed allergen composition may be a unit dosage composition, by whichis meant that it is present in a composition that is configured to beadministered to a subject as a single dose, which single dose may or maynot be part of a dosing schedule made up of two or more unit dosagesthat are administered to a subject over a given a period of time. Whilethe mass of a given unit dosage may vary, in some instances unit dosageshave a mass ranging from 300 mg to 20 grams, such as 300 mg, 400 mg, 500mg, 600 mg, 700 mg, 800 mg, 900 mg, 1000 mg (1g), 1.5 g, 2 g, 3 g, 4 g,5 g, 10 g, 15 g, 20 g, and anywhere in between. In certain embodiments,any two of the mixed allergens are present in equal parts, e.g., in a1:1 ratio, such that each allergen is present in the composition inequal weight. In such embodiments where the mixed allergen compositionincludes three different allergens, the three different allergens arepresent in a 1:1:1 ratio. For example, a mixed allergen composition mayinclude the following allergens in equal parts (e.g., 1:1:1 etc. ratio):walnut, hazelnut, shrimp, salmon, hen's egg, cow's milk, peanut, cashew,almond, and wheat (e.g., about 30 mg of protein each; about 90 mg ofeach protein; or about 300 mg of each protein). In certain embodiments,the mixed allergen composition comprises almond, cashew, walnut,hazelnut, peanut, soy, wheat, hen's egg, cow's milk, white fish, pinkfish, shrimp, and sesame allergens in equal parts with a total estimatedprotein of 400 mg and 400 IU of vitamin D3.

In some embodiments, the mixed allergen compositions include a nutallergen and an animal allergen; and at least one of: a non-nut plantallergen; a biotic agent; and a vitamin. As such, in some embodiments,the mixed allergen compositions include a nut allergen, an animalallergen and a non-nut plant allergen. In such embodiments, the mixedallergen compositions may further include a biotic agent or vitamin orboth a biotic agent and a vitamin. In some embodiments, the mixedallergen compositions include a nut allergen, an animal allergen, andfurther include a biotic agent. In such embodiments, the mixed allergencompositions may further include a vitamin. In some embodiments, themixed allergen compositions include a nut allergen, an animal allergen,and further include a vitamin. In such embodiments, the mixed allergencompositions may further include a biotic agent.

Biotic agents may vary, and include both probiotics and prebiotics. Aprobiotic is generally a live eukaryotic or a prokaryotic organism whichhas a beneficial property when given to a subject. In one aspect, theprobiotic complements the existing microflora in the subject. Hence, theprobiotic agent is a live microorganism which can confer a healthbenefit to a host subject. The probiotic agent may be a culture ofmicroorganisms or provided in a dietary supplement or may be freezedried and reconstituted prior to use. A prebiotic is an agent thatfacilitates or confers growth, maintenance and/or beneficial propertiesof or on the subject's microflora. A prebiotic may include anoligosaccharide and soluble or insoluble fiber material. Examples ofprobiotic agents include, but are not limited to, species ofLactobacillus spp., Escherichia spp., Bacillus spp., Bifidobacteriumspp., Saccharomyces spp. and Streptococcus spp. Specific probioticagents that may be present in the mixed allergen compositions include:Lactobacillus spp., such as Lactobacillus acidophilus, Lactobacilluscasei, Lactobacillus casei Shirota, Lactobacillus casei immunitass,Lactobacillus johnsonii, Lactococcus lactis, Lactobacillus plantarum,Lactobacillus reuteri, Lactobacillus rhamnosus (lactobacillus GG),Lactobacillus salivarius and Lactobacillus helvetirus. The probioticmicroorganisms may be naturally occurring, attenuated or geneticallymodified to introduce new or to alter existing traits. In oneembodiment, the probiotic has been genetically modified to introduce anallergen gene or part or fragment or portion thereof which is expressedto produce recombinant microorganisms which release or expose thesubject's immune system to the allergen or an antigenic fragmentthereof. Hence, the probiotic and allergen may be combined into a singlecomponent of the mixed allergen composition. When present, the amount ofthe biotic agent in the mixed allergen composition may vary. In someinstances, the biotic agent is present in an amount ranging from 1.5 to99.9 wt. %, such as 10 to 25 wt. %.

The mixed allergen compositions may include one or more vitamins, asdesired. Vitamins that may be present in the compositions include, butare not limited to: vitamin A, e.g., in an amount ranging from 1 to35,000 IU; vitamin C, e.g., in an amount ranging from 1 to about 1,000mg; vitamin D, e.g., in an amount ranging from 1 to 4,000 IU; vitamin E,e.g., in an amount ranging from 1 to 450 IU; vitamin K, e.g., in anamount ranging from 1 to 250 mcg; vitamin B-1 (thiamin), e.g., in amountranging from 1 to 15 mg; vitamin B-2 (riboflavin), e.g., in an amountranging from 1 to 17 mg; vitamin B-3 (niacin), e.g., in an amountranging from 1 to 200 mg; vitamin B-5 (pantothenic acid), e.g., in anamount ranging from 1 to 100 mg; vitamin B-6 (pyridoxine), e.g., in anamount ranging from 1 to 30 mg; vitamin B-9 (folic acid), e.g., in anamount ranging from 1 to 4,000 mcg; vitamin B-12 (cobalamin), e.g., inan amount ranging from 1 to 250 mcg; vitamin H (biotin), e.g., in anamount ranging from 1 to 1,000 mcg of vitamin H (biotin); etc.; andcombinations thereof.

The methods described herein may be employed with a variety of differenttypes of subjects, i.e., animals, where the animals are typically“mammals” or “mammalian,” where these terms are used broadly to describeorganisms which are within the class mammalia, including the orderscarnivore (e.g., dogs and cats), rodentia (e.g., mice, guinea pigs, andrats), lagomorpha (e.g., rabbits) and primates (e.g., humans,chimpanzees, and monkeys). In embodiments of the invention, the subjectsare humans. The subject may be infant, juveniles or adults, where insome instances the subject may be pregnant adults, e.g., as described ingreater detail below. As such, in certain embodiments, the subject is apediatric subject younger than 1 year of age, whereas in otherembodiments the subject is older, e.g., 1 year old or more, 5 years oldor more, etc., and including adults. In certain embodiments thepediatric subject is 1 month to 7 years old, e.g., 1 month to 1 yearold, 6 months to 7 years old, 6 months to 1 year old, 2 years to 4 yearsold, or 3 to 7 years old. In certain embodiments, the pediatric subjectis an unborn child of a pregnant woman or a child of a nursing mother.

The dosing schedule may vary as desired, and may depend on a number ofdifferent factors, e.g., purpose of the administration, age of thesubject, condition of the subject, nature of the physiologicallyacceptable composition, etc. In certain embodiments, a mixed allergencomposition or physiologically acceptable composition that includes thesame is administered to a subject on an hourly basis, on an every fewhours basis (e.g., every 2, 3, 4, 6 hours), on a daily basis, on aweekly basis, on a bi-weekly basis, on a monthly basis, one a bimonthlybasis, on a quarter annual basis, on a semi-annual basis, on an annualbasis, etc., for a treatment period of time, which treatment period oftime may also vary, where in some instances the treatment period of timeis 1 day or longer, 1 week or longer, 2 weeks or longer, 1 month orlonger, 3 months or longer, 6 months or longer, 1 year or longer, 2years or longer, 3 years or longer, 5 years or longer, 10 years orlonger, etc., up to the life of the subject. In certain embodiments, thecomposition is administered to a subject for a time or frequency toallow sufficient time for the administration of the composition toinhibit the symptoms of food allergy in a subject.

In some embodiments, the methods are methods of increasing immune healthof the subject. As the methods of these embodiments are methods ofincreasing the immune health of a subject, embodiments of such methodsresult in the subject being better able to have a healthy immuneresponse to a given challenge. Immune health or immune balance may becharacterized as a state in the body where there is not an imbalance ofinflammation. For example, when IgE is decreased and/or IgG4 increasedin plasma and/or Th2 decreased (e.g., as described in greater detailbelow in the Examples section and accompanying figures). The magnitudeof immune health enhancement may vary, where in some instances themagnitude is 2-fold or greater, e.g., 5-fold or greater, including10-fold or greater, e.g., as compared to a suitable control.

In some embodiments, the methods are methods of increasing gut health ofthe subject. As the methods of these embodiments are methods ofincreasing the gut health of a subject, embodiments of such methodsresult in the subject having an enhanced maintenance of healthymicrobiota or improving the resilience of microbiota, for instance, byreducing the numbers or colonization of pathogenic bacteria or virusesand by maintaining and improving the intestinal integrity and barrierfunction. Gut health or gut balance may be characterized as a state inthe body where there is not an imbalance of inflammation. For example,when T cell proliferation is decreased (e.g., as described in greaterdetail below in the Examples section and accompanying figures). Themagnitude of gut health enhancement may vary, where in some instancesthe magnitude is 2-fold or greater, e.g., 5-fold or greater, including10-fold or greater, e.g., as compared to a suitable control.

In some embodiments, the methods are methods of enhancing wellness ormaintaining immune balance of the subject. As the methods of theseembodiments are methods of enhancing wellness of a subject, embodimentsof such methods result in the subject having a quality or state of beinghealthy in body and mind. Wellness may be characterized as a state ofthe body where there is not an imbalance of immune problems (forexample, less IgE, more IgG4, less cell inflammation (e.g., as describedin greater detail below in the Examples section and accompanyingfigures). The magnitude of wellness enhancement may vary, where in someinstances the magnitude is 2-fold or greater, e.g., 5-fold or greater,including 10-fold or greater, e.g., as compared to a suitable control.

In some embodiments, the methods are methods of at least decreasing thepotential of the subject for developing an immune mediated condition,such as an immune-mediated inflammatory disease condition. By at leastdecreasing the potential of the subject for developing an immunemediated condition is meant that the probability of the subject fordeveloping the immune mediated condition is reduced, such that the riskof the subject for developing the immune mediated condition is reduced.For example, to determine risk reduction, if 100 different individualswere administered the composition, 20% or more of the individuals wouldshow a decrease in their immune markers, e.g., IgE, as compared to thecontrol group. The magnitude of the decrease in potential may vary,where in some instances the magnitude is 2-fold or greater, e.g., 5-foldor greater, including 10-fold or greater, e.g., as compared to asuitable control. In some instances, the methods are methods ofpreventing the subject from developing an immune mediated condition. Assuch, the methods of the invention include administering a compositionof the invention to a subject that is not known to have or does not havean immune mediated condition. While the subject may not have or may notbe known to have the immune mediated condition, the subject may be onethat is suspected to be or known to be at risk of developing the immunemediated condition.

Aspects of the invention further include methods of treating a subjectfor an immune mediated condition. By treating or treatment is meant atleast an amelioration of one or more symptoms associated with thedisease condition, e.g., immune mediated condition, afflicting thesubject, where amelioration is used in a broad sense to refer to atleast a reduction in the magnitude of a parameter, e.g., symptom,associated with the pathological condition being treated, etc. As such,treatment also includes situations where the pathological condition, orat least symptoms associated therewith, are completely inhibited, e.g.,prevented from happening, or stopped, e.g., terminated, such that thesubject no longer suffers from the pathological condition, or at leastthe symptoms that characterize the pathological condition.

Treatment may also manifest in the form of a modulation of a surrogatemarker of the disease condition. For example, where the target conditionis an allergy, e.g., as described below, Th2 cell proliferation may bereduced, e.g., as determined using the assay described in the ExamplesSection, below. The magnitude of Th2 cell proliferation reduction mayvary, and in certain instances may range from 1.2× to 10×, such as 2× to4×. Where the target condition is an allergy, e.g., as described below,specific IgG4 levels may be increased, e.g., as determined using theassay described in the Examples Section, below. The magnitude of IgG4level increase may vary, and in certain instances may range from 1.2× to100×, such as 2× to 6×. Where the target condition is an allergy, e.g.,as described below, specific IgE levels may be reduced, e.g., asdetermined using the assay described in the Examples Section, below. Themagnitude of IgE level reduction may vary, and in certain instances mayrange from 1.1× to 7×, such as 2× to 6×.

As summarized above, immune mediated conditions that are the targets ofmethods of the invention include immune-mediated inflammatoryconditions, where such conditions include, but are not limited toconditions characterized by common inflammatory pathways leading toinflammation, and which may result from, or be triggered by, adysregulation of the normal immune response. Examples of immune-mediatedinflammatory conditions include, but are not limited to: allergy,autoimmune diseases, ankylosing spondylitis, psoriasis, psoriaticarthritis, Behcet's disease, arthritis, inflammatory bowel disease(IBD), cardiovascular disease, neuromuscular disease, and infectiousdisease, etc.

In certain embodiments, a disclosed method comprises inhibiting symptomsof one or more food allergies in a human subject, comprising orallyadministering to the subject a composition comprising 2 to 20 differentprotein allergens. In further embodiments, a disclosed method comprisestreating one or more food allergies in a human subject with an existingfood allergy to one or more foods, comprising administering to thesubject a composition comprising 2 to 20 different protein allergens. Incertain embodiments, administration of the composition significantlyinhibits the symptoms of a food allergy in the subject as compared toadministering to the subject a composition that includes only oneprotein allergen. The one or more food allergies may be a single foodallergy or a multiple food allergy. The target allergy may vary widely,where in some instances the target allergy is food allergy, drugallergy, environmental allergy, animal allergy, and insect and/or beeallergy. As such, aspects of the invention include methods of reducingthe risk of a subject for developing an allergy. In certain embodiments,the methods result in the subject having a reduced risk of developing afood allergy to a food allergen that is not present in the mixedallergen composition that is administered to the subject. For example,the administered composition may provide to the subject allergenprotection for a nut protein in the formulation as well as a nut proteinnot found in the formulation. In certain embodiments, the reduced riskfor a first food allergen is reduced to a greater extent using the mixedformulation than would be achieved using a formulation with only asingle allergen. For example, feeding a mixed allergen formulation asdescribed herein can result in lower risk of allergy development for anallergen (e.g., with respect to Th2/IgE/IgG4 analyses, as shown below)than if the formulation only included that single allergen. In somecases, this phenomenon is referred to as “synergy” (e.g., cashewsynergizes with pistachio, walnut with pecan, shrimp with lobster (andother crustacean), and vice-versa). Where the method is a method oftreating the subject for the allergy, as reviewed above the method mayresult in at least an amelioration of one or more symptoms associatedwith the allergy, e.g., as described above. Allergy symptoms that may beameliorated, but are not limited to: eczema, asthma, atopic dermatitis,bronchospasm, cough, rhinorrhea, angioedema, gastric hypermotility,urticaria (hives), pruritis, fatigue, bradycardia, allergic rhinitis,allergic conjunctivitis, and/or hypotension. The magnitude of thesymptom reduction may vary, where in some instances the magnitude is2-fold or greater, e.g., 5-fold or greater, including 10-fold orgreater, e.g., as compared to a suitable control. In some instances,treatment of an allergy results the subject being cured of the allergy,such that the subject no longer suffers from the allergy. In someembodiments of allergy treatment methods, the methods includeadministering to a subject a mixed allergen composition that includes anut allergen; an animal allergen; and at least one of: a non-nut plantallergen a biotic agent; and a vitamin, such as described above.

Also provided are methods of significantly reducing the probability ofdeveloping one or more food allergies in a subject. In certainembodiments, a subject is an unborn child of a pregnant woman or a childof nursing mother, and the method comprises administering to thepregnant or nursing mother a disclosed composition. In certainembodiments, the subject is a child having a developing immune system.Further provided are methods for desensitizing a human to one majorallergen or to two or more major allergens comprising administering tothe human a food product comprising two or more allergens, wherein thecomposition is administered according to a schedule of treatment.

In some instances, the methods are methods of treating a subject for aneosinophilic disorder. Eosinophilic disorders are disorderscharacterized by the occurrence of eosinophils in above-normal amountsin various parts of the body. Eosinophilic disorders of interestinclude, but are not limited to: eosinophilic esophagitis (esophagus);eosinophilic gastritis (stomach); eosinophilic enteritis (smallintestine); eosinophilic colitis (large intestine); hypereosinophilicsyndrome (blood and any organ); and the like. In some instances themethods are methods of reducing the risk of a subject for developing aneosinophilic disorder. The magnitude of the risk reduction may vary,where in some instances the magnitude is 2-fold or greater, e.g., 5-foldor greater, including 10-fold or greater, e.g., as compared to asuitable control.

In some instances the methods are methods of treating a subject forinflammation, where the inflammation may be a symptom of a variety ofdifferent disease conditions. Disease conditions in which theinflammation thereof may be treated according to embodiments of theinvention include, but are not limited celiac disease, multiplesclerosis, inflammatory bowel disease, eosinophilic diseases, allergy,food allergy, etc.

Aspects of the invention further include methods of at least decreasingthe potential of a fetus or suckling infant for developing an immunemediated condition, such as an immune-mediated inflammatory diseasecondition, e.g., allergy, such as described above. By at leastdecreasing the potential of the fetus or suckling infant for developingan immune mediated condition is meant that the probability of the fetusor suckling infant for developing the immune mediated condition isreduced, such that the risk of the fetus or suckling infant fordeveloping the immune mediated condition is reduced. The magnitude ofthe decrease in potential may vary, where in some instances themagnitude is 2-fold or greater, e.g., 5-fold or greater, including10-fold or greater, e.g., as compared to a suitable control. In someinstances, the methods are methods of preventing the fetus or sucklinginfant from developing an immune mediated condition. As such, themethods of the invention include administering a composition of theinvention to a mother of a fetus or suckling infant that is not known tohave or does not have an immune mediated condition. While the fetus orsuckling infant may not have or may not be known to have the immunemediated condition, the fetus or suckling infant may be one that issuspected to be or known to be at risk of developing the immune mediatedcondition.

In certain embodiments, the mixed allergen composition orphysiologically acceptable composition that includes the same isadministered to a pregnant or nursing mother of a pediatric subject,fetus or suckling infant. For example, the mixed allergen composition orphysiologically acceptable composition that includes the same may beadministered to a mother pregnant with the fetus. In such instances, themixed allergen composition or physiologically acceptable compositionthat includes the same may be administered to the mother using anyconvenient dosing schedule, e.g., as described above, starting at anyconvenient time during the pregnancy, e.g., at the start of the secondtrimester, at the start of the third trimester, etc. Where the method isa method of reducing risk in a suckling infant, the mixed allergencomposition or physiologically acceptable composition that includes thesame may be administered to a mother that is breast feeding the infant.In such instances, the mixed allergen composition or physiologicallyacceptable composition that includes the same may be administered to thebreast feeding mother using any convenient dosing schedule, e.g., asdescribed above, starting at any convenient time during the breastfeeding, e.g., at the start of lactation, 1 week after lactationcommencement, etc.

Practice of the invention will be more fully understood from theforegoing examples, which are presented herein for illustrative purposesonly, and should not be construed as limiting the invention in any way.

EXAMPLES Example 1 Mixed Allergen Assay #1 Study Design andPopulation/Allergen Treatment

For each allergen or allergen mix listed below (the allergen groups),five subjects from each of five different age groups were fed a total of300 mg of the allergen or allergen mix daily for one year. The onlyexceptions are for Formula 1 at 3× (i.e., 3× mix) and Formula 1 at 10×(i.e., 10× mix), in which the subjects were fed 900 mg and 3,000 mg ofthe formula on a daily basis, respectively. Allergen mixes wereformulated at a 1:1 ratio. Thus, for an allergen mix with 2 allergens,the mix would include 150 mg of each. Five subjects were included ineach age group that were not fed an allergen (Not Treated, or NT group,listed last in FIGS. 1-3).

The following 18 groups were randomized equally. Children ate (daily)either 1) cashew alone, 2) cashew and pistachio, 3) walnut alone, 4)walnut and pecan, 5) a protein mix containing equal parts walnut,hazelnut, shrimp, salmon, hen's egg, cow's milk, peanut, cashew, almond,and wheat (1× mix supplement at equal protein ratios), 6) a 3× mixsupplement of the same proteins as the lx mix, 7) a 10× mix supplementof the same proteins as the 1× mix, 8) control group that followed AAPguidelines prior to October 2015, 9) white fish alone 10) white fish andpink fish, 11) shrimp alone, 12) shrimp and crab, 13) peanut alone, 14)peanut and soy, 15) hazelnut alone, 16) almond alone, 17) cow's milk,18) hen's egg, Supplement mixes were added to breast milk or to relevantfood items eaten (i.e. apple sauce, pudding, shakes, yogurt) by thedifferent age groups, eaten freshly, and parents were told to watch anddocument the full intake of the supplement daily. The protein mix wasapproximately a teaspoon daily.

Each treatment group consisted of five children from each of thefollowing five age groups: 4 to 6 months, 7 to 12 months, 1 to 3 years,3 to 5 years, and 5 years or older. The subjects were not selected basedon observed or suspected food allergy (or other allergy) profile, andthus the cohort of subjects tested included those who may have, or havethe propensity to develop, a food allergy as well as those who do not.Children were both low- and high-risk (defined by a first degreerelative with atopic dermatitis or two first degree relatives withatopy) for developing allergies, but none had a doctor's diagnosis offood allergy.

Blood Sample Collection

Peripheral blood mononuclear cells (PBMCs) and plasma were extractedfrom blood via ficoll procedure and stored in liquid nitrogen and at−80° C., respectively. Allergen-specific IgE and IgG4 were measuredusing a standard ImmunoCAP assay (Phadia, Uppsala, Sweden).

Stimulation and Enumeration of Th2 Cell Subsets

PBMCs from subjects were labeled with carboxyfluorescein diacetatesuccinimidyl ester (CFSE) and cultured with the same food allergen orfood allergen mix that was fed to the participant at 100 μg/mL oranti-CD3/CD28 (to test for nonspecific proliferation capacity) for 7days to identify T cell subsets. At day 7, cells were washed and stainedfor surface CD4, CD25, CD127, CD45RO, CD45RA, CD40L, and CD69 andintracellular Foxp3 and IL-10 along with Live/Dead staining (Invitrogen)(see T-cell flow cytometry method below). Th2 cells were defined as thecells that proliferated in response to food allergen (CFSE1o) and wereCD41 IL-4, IL-13 cells. Antigen-induced T cells were also identified byisolating CD40L and CD69 double-positive cells after antigenstimulation.

Cells were fixed with Lyse/Fix PhosFlow buffer (BD Biosciences). Forintracellular staining, fixed cells were permeabilized with Perm BufferIII (BD Biosciences) at 48° C. for 30 minutes, followed by staining at48° C. for 20 minutes. Flow cytometry was performed with an LSRII flowcytometer (BD Biosciences). Viable cells were identified with aLive/Dead probe (Invitrogen). Phenotypes of T cells were detected withantibodies against surface CD3 (UCHT1), CD4 (SK3), CD25 (4E3), CD127(SB199), CD45RO (UCHL1), CD45RA (HI100), CD62L (DREG-56), CCR4 (1G1),and CCR8 from BD Biosciences; CCR7, CD69, and CD40L and intracellularIL-10 (JES3-19F1), IL-4 (MP4-25D2), and IL-13 (JES10-52A2) from BDBiosciences; Helios (22F6) from BioLegend; anti-CD49b from BioLegend;anti-LAG3 from R&D Systems (Minneapolis, Minn.); and Foxp3 (150D) fromBioLegend and stained per the manufacturer-recommended protocol.

Measurement of Antibody Titers

Total and allergen-specific blood IgE and IgG4 levels were measured inall subjects in the Clinical Laboratories at Stanford Hospital andClinics using a standard ImmunoCAP assay (Phadia, Uppsala, Sweden).

Statistical Analysis

Comparisons between cohorts, and between baseline and 1 year and controlgroups were evaluated with the nonparametric Mann-Whitney test, pairedWilcoxon test, and 1-way and 2-way ANOVA (GraphPad Prism Software 5.0;GraphPad Software, La Jolla, Calif.), as appropriate. A P value of lessthan 0.05 was considered statistically significant.

Compliance and Safety

Compliance was excellent with no dropouts in control arm and fifteendrop outs in ingested arms total. Of those who completed the study,there were only 90 missed doses (out of a total of 240,810) asdetermined by reviews of electronic dietary records (see Table 2).Adverse events were minimal in the active with only 21 cases of mildskin rash (21/660; 0.03%). Adverse events in the control group consistedof 3 cases of mild skin rash (3/30; 10%). 15 dropped out of the study atabout 1 year in the active arm due to non-compliance, not due to safetyissues.

Th2 Cell Proliferation

PBMCs from each subject in allergen groups 1 to 18 were stimulated exvivo with the allergen or allergen mix fed to the subject for 7 days andTh2 cell proliferation was analyzed (as described above). It is notedthat for Formula 1 3× and Formula 1 10× groups, the PBMCs werestimulated with 3× and 10× the amount of allergen ex vivo, respectively(i.e., 300 μg/mL and 1000 μg/mL, respectively).

As shown in FIG. 1, stimulation of PBMCs from cohorts fed singleallergens or allergen mixes had a lower degree of Th2 proliferation thancontrols (non-treated 1-year and non-treated baseline), indicatingdecreases in allergic response on exposure to allergens or allergenmixes. Additionally, the allergen mixes containing 10 allergens had thelowest degree of Th2 proliferation, significantly more than that ofcohorts containing allergen mixes of 2 allergens or single allergens,indicating that diversity of food proteins further decreases allergicresponse.

Specifically, subjects in allergen groups 1 to 4 and 9 to 18 showed asomewhat reduced Th2 proliferation in response to allergen stimulationas compared to the non-treated control (Group 8; Baseline-NT). However,Th2 cell proliferation in PBMCs from subjects in allergen groups 5 to 7(fed increasing amounts of Formula 1), who were fed formulations having10 separate allergens, as described above, had significantly reduced Th2cell proliferation as compared to both the control group (NT) as well asall other antigen groups (1 to 4 and 9 to 18). This phenomenon was seenfor all subjects in all allergen groups at all ages tested, includingfor the different doses (1×, 3×, and 10× allergen mix).

Immunoglobulin Analyses

In addition to the Th2 proliferation assay above, plasma from subjectsin allergen groups 1 to 18 were analyzed for the presence of IgG4 andIgE antibodies (using standard methods, as described above), the formerbeing an indicator of a non-allergenic or non-inflammatory (oranti-allergenic or non-inflammatory) state and the latter an indicatorof pro-allergenic or pro-inflammatory a sate.

Increased IgG4 levels indicate a protective anti-inflammatory state. Asshown in FIG. 2, when compared to baseline, samples from participantsfrom all cohorts showed an increase in IgG4, with the 10-allergen mixformula showing greater IgG4 levels than from those from cohorts fedsingle allergens or 2-allergen mixes. No significant difference in IgG4was observed between the 1×, 3×, and 10× allergen mixes containing 10allergens.

Specifically, subjects in allergenic groups 1 to 4 and 9 to 18 showedmoderately increased levels of IgG4 as compared to the baseline group(Group 8; NT). However, allergen groups 5 to 7 (fed increasing amountsof Formula 1) showed significantly increased levels of IgG4 as comparedto both the baseline group as well as all other antigen groups (1 to 4and 8 to 18). This result is consistent with the results for Th2 cellproliferation as described above. Specifically, increased levels of IgG4in the plasma and reduced Th2 cell proliferation are indicators of areduced or non-allergenic or non-inflammatory state in a subject.

Increased specific IgE is indicative of an inflammatory allergic state.As shown in FIG. 3, samples from participants from all cohorts fedallergens or allergen mixes showed decreases in IgE, with the plasma ofthose fed the 10-allergen mix (1×, 3×, and 10× formulations) having IgElevels below the assay detection level. In particular, subjects inallergenic groups 1 to 4 and 9 to 17 showed significantly higher levelsof IgE in the plasma as compared to allergen groups 5 to 7 (fedincreasing amounts of Formula 1). Indeed, IgE levels in the allergengroups 5 to 7 were below the level of detection of the assay.

These results are consistent with the results for Th2 cell proliferationand the IgG4 levels as described above. Specifically, low levels of IgEand increased levels of IgG4 in the plasma coupled with reduced Th2 cellproliferation are indicators of a reduced or non-allergenic ornon-inflammatory state in a subject.

It is clear from the results above that continual feeding of a complexmixture of food allergens to subjects (e.g., in the form of Formula 1described above) at a very young age can prophylactically protect asubject from developing an allergenic or inflammatory immune profile toa wide variety of antigens. In other words, this process can induce in asubject a non-allergenic or non-inflammatory (or anti-allergenic oranti-inflammatory) state. Of particular interest in the results shownherein is the indication that feeding antigens in a complex mixtureprovides broad spectrum protection against developingallergies/inflammation that is superior to single or even doubleallergen formulas that target a single allergen (as in allergen groups1, 3, 11, 13 and 15 to 18 above) or multiple related allergens (e.g., asin allergen groups 2, 4, 10, 12, and 14 above).

The above shows that feeding subjects complex antigen mixtures will notonly protect against the development of allergies and/or inflammation tothe allergens/antigens in the complex mixture, but also to allergens orantigens that are not present in the complex mixture. In essence,feeding complex food antigen mixtures creates a general anti-allergenicor anti-inflammatory state in a subject that broadly prevents thedevelopment of allergies or inflammatory state, even toallergens/antigens not yet fed to the subject.

Mixed Allergen Compositions (+Probiotics and/or Vitamin)

Subjects were also fed compositions comprising allergen mixes in a 1:1blend with probiotics and/or vitamins. The details of the compositionsthat were used are shown below:

-   -   1. Formula 1 at 1× (equal parts walnut, hazelnut, shrimp,        salmon, hen's egg, cow's milk, peanut, cashew, almond, and        wheat)    -   2. Non-treated control (NT)    -   3. 1 part Formula 1 at 1× (as above) with 1 part vitamin D (400        IU; Vitamin in this instance was Poly Vi Sol brand for        children).    -   4. 1 part Formula 1 at 1× (as above) with 1 part probiotics        (Probiotic in this instance was Lactobacillus; Culturelle        brand).    -   5. 1 part Formula 1 at 1× (as above) with 1 part vitamin D (400        IU; Vitamin in this instance was Poly Vi Sol brand for children)        and 1 part probiotics (Lactobacillus; Culturelle brand).    -   6. 1 part Formula 1 at 1× (as above) after baking (15 min at        350° F.).    -   7. 1 part Formula 1 at 1× (as above) after incubation at pH=2        for 15 min.        Each composition had 300 mg each of the dietary supplement        mixture, probiotics, and/or vitamins when present. Mixtures at        pH 2 were incubated in vinegar for 40 min at room temperature        before using. Mixtures that were baked were heated for 40 min at        350° F. Control received no dietary supplement.

T-Cell Proliferation

PBMCs from each subject were stimulated ex vivo with the allergen ormixed compositions described above and Th2 cell proliferation wasanalyzed as described above. As shown in FIG. 4, PBMCs on stimulation exvivo with the allergen or allergen mix under the following conditionsshowed similar Th2 proliferation: lower pH, addition of probiotics,addition of vitamin D, or after baking.

Subject samples showed similar Th2 proliferation decreases with themixture or under different conditions with the mixture. This phenomenonwas seen for all subjects in all allergen groups and at all ages tested.

Immunoglobulin Analyses

In addition to the Th2 proliferation assay above, plasma from subjectsin allergen groups were analyzed for the presence of IgG4 and IgEantibodies (using standard methods, as described above), the formerbeing an indicator of a non-allergenic or non-inflammatory (oranti-allergenic or anti-inflammatory) state and the latter an indicatorof pro-allergenic or pro-inflammatory state.

As shown in FIGS. 5 and 6, subjects showed moderately increased levelsof IgG4 as compared to control group and significantly higher levels ofIgE in the plasma. As shown in FIG. 5, similar IgG4 levels were observedunder the following different conditions with the allergen-mix: lowerpH, addition of probiotics, addition of vitamin D, or after baking. Asshown in FIG. 6, no IgE levels were observed in response to thedifferent tested mixed allergen compositions. There were similar effectsseen with the mixture or under different conditions with the mixture,with similar IgE levels observed under the following differentconditions with the allergen-mix: lower pH, addition of probiotics,addition of vitamin D, or after baking.

T-Cell Proliferation

T cell proliferation was performed (please see methods section above)and data presented in FIG. 7. The data show anti-inflammatory propertiesto gluten (i.e., celiac agent), and insulin (i.e., diabetes agent) andbacterial flagellin (inflammatory bowel disease agent). Thisdemonstrates that the mixture could also decrease inflammatory statesinvolved in diseases like celiac, diabetes and inflammatory boweldiseases.

Example 2 Mixed Allergen Assay # 2 Study Design and Population/AllergenTreatment

Infants and children were seen in a research setting from 4 weeks old to3 years of age. A single allergen or allergen mix supplement wasconsumed orally daily for one year.

Subjects were fed a total of 300 mg of a single allergen or allergen mixdaily for one year. The only exceptions are for Formula 1 at 3× (i.e.,3× mix) and Formula 1 at 10× (i.e., 10× mix), in which the subjects werefed 900 mg and 3,000 mg of the formula on a daily basis, respectively.Allergen mixes were formulated at a 1:1 ratio. Thus, for an allergen mixwith 2 allergens, the mix would include 150 mg of each. Thirty subjectswere included that were not fed an allergen (control group listed).

There was similar distribution of age and sex, and all children werebreast fed for at least the first 4 months of life. There was similardistribution of high risk and low risk for food allergy (i.e. high riskare those infants born to a family with one first degree relative withfood allergy or one first degree relative with atopic dermatitis or twofirst degree relatives with atopic disease). None had a doctor'sdiagnosis of food allergy.

The subjects were not selected based on observed or suspected foodallergy (or other allergy) profile, and thus the cohort of subjectstested included those who may have, or have the propensity to develop, afood allergy as well as those who do not. The total number of subjectswas 60 including control.

Milk: Organic non-fat dry milk powder from “Now Foods”        Bloomingdale, Ill. 60108.    -   7. Control

The total dose of allergens used was about 300 mg total for singleallergens and for allergen mixes unless specified otherwise. A 3× and10× formulation containing allergens each containing about 900 mg and3000 mg total allergen, respectively, were also used in the study.Allergen mixes were formulated so that equal amounts of each allergenwere present in the mix. Mixing occurred prior to ingestion.

Blood Sample Collection

Peripheral blood mononuclear cells (PBMCs) and plasma were extractedfrom blood via ficoll procedure and stored in liquid nitrogen and at−80° C., respectively. Allergen-specific IgE and IgG4 were measuredusing a standard ImmunoCAP assay (Phadia, Uppsala, Sweden).

Stimulation and Enumeration of Th2 Cell Subsets

PBMCs were labeled with carboxyfluorescein diacetate succinimidyl ester(CFSE) and cultured with the same food allergen or food allergen mix at100 μg/mL or anti-CD3/CD28 (to test for nonspecific proliferationcapacity) for 7 days to identify T cell subsets. At day 7, cells werewashed and stained for surface CD4, CD25, CD127, CD45RO, CD45RA, CD40L,and CD69 and intracellular Foxp3 and IL-10 along with Live/Dead staining(Invitrogen). Th2 cells were defined as the cells that proliferated inresponse to food allergen (CFSE1o) and were CD41 IL-4, IL-13 cells.Antigen-induced T cells were also identified by isolating CD40L and CD69double-positive cells after antigen stimulation.

Measurement of Antibody Titers

Total and allergen-specific blood IgE and IgG4 levels were measuredusing a standard ImmunoCAP assay (Phadia, Uppsala, Sweden).

Statistical Analysis

Comparisons between cohorts, and between baseline and 1 year and controlgroups were evaluated with the nonparametric Mann-Whitney test, pairedWilcoxon test, and 1-way ANOVA (GraphPad Prism Software 5.0; GraphPadSoftware, La Jolla, Calif.), as appropriate. A P value of less than 0.05was considered statistically significant.

Compliance and Safety

Compliance was excellent with no dropouts in control arm or fed arm. Ofthose who completed the study, there were only 3 missed doses (out of atotal of approximately 10,950) as determined by reviews of electronicdietary records (see Table 3). Adverse events were minimal in the fedarm with only 2 cases of mild skin rash (2/30; 7%). Adverse events inthe control group consisted of 5 cases of mild skin rash (5/30; 17%).

Th2 Cell Proliferation

PBMCs were stimulated ex vivo with the an allergen or allergen mix fedto the subject for 7 days and Th2 cell proliferation was analyzed (asdescribed in the Methods section above). It is noted that for Formula 13× and Formula 1 10×, the PBMCs were stimulated with 3× and 10× theamount of allergen ex vivo, respectively (i.e., 300 μg/mL and 1000μg/mL, respectively).

As shown in FIG. 8, PBMCs from fed subjects stimulated with singleallergens or allergen mixes had a lower degree of Th2 proliferation thanstimulated PBMCs from control subjects, indicating decreases in allergicresponse on exposure to the allergen mixes.

Immunoglobulin Analyses

In addition to the Th2 proliferation assay above, plasma from subjectswere analyzed for the presence of IgG4 and IgE specific antibodies(using standard methods, as described above), the former being anindicator of a non-allergenic or non-inflammatory (or anti-allergenic ornon-inflammatory) state and the latter an indicator of pro-allergenic orpro-inflammatory state.

Increased IgG4 levels indicate a protective anti-inflammatory state. Asshown in FIG. 9, when compared to baseline, samples from fedparticipants showed an increase in IgG4, with samples from participantsfed the allergen mix formula showing greater IgG4 levels than those fromcohorts fed single or double food compositions. No significantdifference in IgG4 was observed between samples from participants fedthe 1×, 3×, and 10× allergen mixes or with vitamin D3.

Increased specific IgE is indicative of an inflammatory allergic state.As shown in FIG. 10, samples from participants fed single food and foodmixes showed decreases in IgE, with the lowest levels seen for samplesfrom participants fed the 1×, 3×, and 10× allergen mixes.

These results are consistent with the results for Th2 cell proliferationand the IgG4 levels as described above. Specifically, low levels of IgEand increased levels of IgG4 in the plasma coupled with reduced Th2 cellproliferation are indicators of a reduced or non-allergenic ornon-inflammatory state in a subject. It is clear from the results abovethat continual feeding of a simple or complex mixture of food allergensto subjects (e.g., in the form of Formula 1) at a very young age canprophylactically protect a subject from developing an allergenic orinflammatory immune profile to a wide variety of antigens. In otherwords, this process can induce in a subject a non-allergenic ornon-inflammatory (or anti-allergenic or anti-inflammatory) state.Although a single allergen product showed evidence of effect, ofparticular interest in the results shown herein is the indication thatfeeding antigens in a complex mixture provides broad spectrum protectionagainst developing allergies/inflammation that is superior to single oreven double allergen formulas that that target a single allergen.

The above shows that feeding subjects simple or complex antigen mixtureswill not only protect against the development of allergies and/orinflammation to the allergens/antigens in the complex mixture, but alsoto allergens or antigens that are not present in the complex mixture. Inessence, feeding complex food antigen mixtures creates a generalanti-allergenic or anti-inflammatory state in a subject that broadlyprevents the development of allergies or inflammatory state, even toallergens/antigens not yet fed to the subject.

Example 3 Therapeutic Applications of Mixed Allergen Compositions

The mixed allergen compositions disclosed herein will be further testedfor their ability to treat or prevent a range of allergic diseases,e.g., asthma, atopic dermatitis, allergic rhinitis, allergicconjunctivitis, food allergies, insect allergies, or drug allergies.

The mixed allergen compositions will be given to subjects via differentroutes, e.g., orally, mucosal, subcutaneously, or cutaneously. Therapywill be daily or weekly, starting at small amounts (about 1 mg or less).As appropriate, it will be possible to stay on the same amount orincrease by 5-100% each week, over time, to larger amounts (about 300 mgor higher). Blood from subjects will be collected at baseline and thenduring and after therapy. Biomarkers would be predicted to show improvedimmune balance and immune protection against allergy inflammation. Forexample, Th2 proliferation and/or IgE to the antigen would decrease andIgG4 could increase over time during the exposure to the mixed allergencompositions.
